*downloads* *resurrects* Dooooooooooooooods!!! She's gonna be in AVATAR?!?!? (This is, of course, NOT Avatar: The Last Airbender we're talking about. Cos gods KNOWS the Hollywood bastards already have that lined up to be massacred at a later date.)

From IMDB: Michael Biehn was considered for the role of Col. Quaritch. He met with James Cameron three times and saw some of the 3D footage, but in the end it simply came down to the fact that Cameron didn't want people thinking it was Aliens (1986) all over again, as Sigourney Weaver had already been cast.
